SIGN-RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. '7 62,192, dated June *7, 1904.

Application filed January 11,1904. Serial No. 188,528. (No modelh To all whom It may concern.-

Be itknown that I, CLARENCE D. PLATT, a citizen of the United States of America, residing in Bridgeport, in the county of Fairfield,

State of Connecticut, have invented an Improved Sign-Receptacle, of which the following is a specification.

The object of my invention is to improve the construction of receptacles for incandescent electric lamps, more particularly such receptacles as are designed for use on signboards.

In the accompanying drawings, Figure 1 is a perspective view of my improved receptacle,

5 and Figs. 2 and 3 are sectional views taken a right angles to each other.

As is common in this class of receptacles, the body is made of porcelain or other suitable insulating material and comprises a hollow cylindrical part Awith a flanged base B. WVithin the interior of the hollow cylindrical part are secured the lamp-holding terminals, which in the drawings are shown as of the Edison type and comprise a threaded metal 5 shell C, secured by screws 0 to the base, Fig. 2, and a central contact D, with spiral spring (Z, also secured to the base. The flange b of the base B has the usual holes Z) for the screws, by which the receptacle is to be secured to the 3 sign-board.

On the back or outer surface of the base B is a projecting annular flange E at a little distance from the outer margin of the base, and I prefer to flare the outer wall of this flange,

as shown at 0. This flange is notched at diametrically opposite points a e for the passage of the outer ends of the terminal plates C and D. The plate C is preferably forked at its inner end, as illustrated in Fig. 1, with 4 the inner forked ends tapped to receive the threaded ends of the securing-screws c to make mechanical and electrical connection with the screw-shell C, as shown in Fig. 2. The plate D is a straight plate with its inner end tapped to receive the threaded end of the central contact-screw D, as shown in Figs. 2 and 3. The outer ends of both plates C and D are tapped to receive the binding-screws a" g for the linewires and are preferably bent up a little at their extreme outer ends to aid in retaining the wires, as usual. With the exception of this slight bend both plates are perfectly flat, and therefore very easily and economically made, and this is due to the described construction of the base of the receptacle. Furthermore, the making of the flange E at a distance from the outer margin of the base enables me to make the plates C D quite short and projecting but little, if at all, beyond the base, and yet allowing convenient application and connection of the wires. After the plates C D have been secured in place I prefer to pour suitable insulating material while in a molten condition into the circular chamber formed and inclosed by the flange E. This insulating material on hardening effectually separates the two plates C D from each other and prevents possibility of a short circuit being formed between them.

I claim as my invention A sign-receptacle, having lamp-terminals and having on the back of the insulating-base a projecting annular flange at a short distance from the outer margin of the base, opposite notches in said flange and plates projecting through said notches for connection at their inner ends to the lamp-terminals and carrying at their outer ends binding-screws, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
